To all w/Lom t may concern-.f

Be it known that I, CHARLES H. KNoBBs, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Port Lights, of which the following is a specification. The invention relatesto ships and more particularly to the port-lights thereof, and has for an'object to provide a port-light providing ventilation `to an interior portion of a vessel when the port-light is open and also adapted for the passage of iight to an interior portion of a ship.

The invention comprehends among other features the provision of a port-light which is particularly adapted for use on the hulls of vessels or other parts of a'ship, for the purposesV of providing ventilation oi light, and to this end, contemplates a glass frame which can be arranged in an open or closed position, relative to its supporting port-light frame, a vsuitable cover being also provided which latter element can be closed upon the glass frame, all of the parts when closed, providing a locked structure which will eX- clude the light from the interior of the vesseland also prevent the ingress of water.

In the further disclosure of the invention, reference is to be had tothe accompanying drawings, constituting a part of this speci* fication, inwhich similar characters of reference denote corresponding parts in all the views, and in which,

Figure l-'is a perspective view of the improved port-light, showing the glass frame and cover in closed position.

Figure 9-is a fragmentary'perspective view showing a. slightly modified form of locking device.

Referring more particularly to the drawings, the numeral 10 indicates a port light frame,` of substantially circular form, suitably bolted to the side 11 of a vessel or the like to register with an opening 12 therein. Suitably seated in the outer face of the port light frame is an annular gasket 13, and adjacent thereto vare the equally spaced integral locking lugs 14, each of which is formed with a cam like under surface 15 inclined to the plane of the face of frame 10. The port light frame is also formed with a plurality of spaced outwardly projecting lugs 16 having bearings to receive a pintle 17 which extends loosely through elongated openings 18, formed in hinge members 19 which projectl from the periphery of a glass frame 20 having a suitable glass or light 21 secured therein. The glass frame 20 can be swung upon the portlight frame 10 through the medium of the pintle 1 7 and when the glass frame fits down upon the port light frame, an annular seat 22 thereof will bear against the gasket 13 A cover 23 is provided for the glass frame 20 and the cover is formed with a plurality of hinge elements 24 having elongated openings 25 in which the pintle 17 loosely en: gages, so that the cover and glass frame 2O are both pivoted to swing upon the pintle 17 which is therefore common to both the glass frame and the cover. The cover 23 is provided with a gasket 26 which when the cover is closed down upon the glass frame. Causes the gasket to bear against the annular rim or seat 27 on the glass frame. It should be particularly noted that the pintle or hinge connection between the glass frame and the port-light frame` and the cover and the portlight frame, provided for independent swinging movements of the glass frame and the cover in a common path. lt will be noted however that because of the elongated openings in the hinge members of the glass frame and cover, the said glass frame and the cover, each has an independent movement apart from' its swingingthereof, upon the portlight frame; that is to say, the glass frame after beingswung at an angle to tue plane of the port-light frame, can also be moved toward or away from the gasket' i3 against which the glass frame is adapted to seat and so also the cover 23 apart from its swinging movement relative to the glass frame and the port-light frame, can be moved bodily toward or away from the rim 2T of the gl: gls frame. The object in providing independe movement of the glass frame, apart from its swinging movement and so also with the cover, is to permit of uniformly and securely clamping the glass frame evenly aga-inst the gasket on the port-light frame and therefore also to permit of clamping the cover uniformly and evenly against the rim 27 of the glass frame. If the glass frame and cover were only mounted to swing, :it would be iin.- possible to obtain an equal clamping pressure entirely around the particular gaskets and thus an effective joint in each instance would not be obtained.

To effect the proper clamping and locking of the glass frame with the port-light frame, a plurality of clamping and locking" de f'icesor dogs 28 are provided, each having a suitable handle 29 and a projection 30. These clamping and locking devices 2S are suitably mounted to swing upon ears 3l, projecting .from the glass frame and the projections 30 are adapted to engage with and seat in the particular lugs 14: formed on the port-light frame, with faces of the Drojeftions 30 adapted to hear against Ythe inclined or cam-like surfaces l5 of the lugs, thus insuring a positive clamping of the glass frame against the gasket 13, regardless of the hinged or swinging connection of the` glass frame with the port-light fra-nie and therefore when the handles Iof the clamping and locking devices 2S are actuated, the projections 30 operating over'theV inclined surfaces l5 of the lugs ifi, will not euly clamp but securely lock the glass frame uniformly and evenly against the gasket on lthe portlight frame.

In a similar manner the cover 9.3 is provided with cars. which pivotally support clamping and locking devices 3?, having handles 234- and proiections S5, the latter-being adapted to engage in and with lugs Boon the periphery of the glass frame andr also adapted to have faces thereof, operato over inclined surfaces 3"? on the lugs so that the gasket 2G will he uniformly pressed down noon the annular rini of the odass frameand the operation of the clamping and locking devices 33 will insure a positive locking of the cover to the glass frame, regardless of the hinged or swinging connection of the.

cover relative to the port-light frame.

It may be here stated that it is important to have the glass frame slip readily into position to seat upon the gasket of the portlight frame and to effect this result, edges 58 of the lugs i4, are rounded olf to form guides, tending to lguide the glass frame into proper seating position, projections 39 of the clamping and locking devices or dogsfl, being adapted to extend into recesses or cupped out portions et() in the face of the port-light frame. i

From the foregoing description, it will be see-n that the glass frame can loe swung relative to the port-light frame and independently of the cover and that the cover can be swung relative to the port-light frame independently of the glass frame; further that the glass frame can be secured in clamped and locked position upon the port-light frame independently of the cover.l and that the cover can be clamped and locked to the glass frame independently of the clamping and locking relation ofthe glass frame to the port-light frame. noted that with this construction, the glass frame swings in the path of swinging movement ofthe cover and vice versa,rthis being due to the provision of a single hinge element to which both the cover and the glass frame are common. It is to be observed that after thelr glass frame has been swung from an open to a closed position, the operation of the clamping and locking devices move the glass frame forward or against the portlight frame to the clamping position, this movement being one which is in the plane of the port-light frame so that theglass frame is capable of a swinging movement relative to the port-light f1 ame and also capable of a backward and forward movement relative to the port-light frame. Likewise, the cover can be swung to an angle at a plane ofthe glass frame and independently moved hackwa-rd-or forwardV relative to the glass frame in order that thecover can'loe clamped uniformly aroundits entire periphery to the glass frame,l when the clamping and locking devices thereof are engaged with the particular lugs 36, provided forthe purpose.y

ln Figurey 9, l show a slightly modified form of my device and in which instead of'. providing handles 29fl'or theclamping and lockingdevices 28 and handles 34 for the clamping and locking devices 33, l merely. substitute in place of the handles, enlarged` portions 41, respectively,V which may, -in cross section` be of a hexagonal construction and will, when an Yordinary Yor particular form of wrench is applied thereto, permit of actuating theclamping and lock ing devices 28, 33, to lock the glass frame to the port-light frame or the coverto the glass frame or vice versa. This particular form of construction is employed in cases where port-lights are placed within the reach of passengers on a ship, who, if the clamping and locking device were provided with handles, might endeavor to operate the portlight or unloosen the cover or glass frame and thus result in subsequent damage or injury to the vessel, in the event of a heavy sea or storm, enabling the water to pass through between the cover and glass frame, or the glass frame and the port-light trame, to the interior of the vessel.

` It will be understood that I do `not limit myself to the particular form o'f construction set forth in the specification and illustrated in the drawings, that various slight changes may be made without departing from the spirit of the invention and that the scope thereof is dened in the appended claims.
